  • Flywheel

    What was the reason to build flywheels so heavy? Common to shave pounds off when doing an overhaul. I'm working on another car with a smaller engine than an A and the flywheel weighs close to #50. There must have been an engineering reason.

    that is how Henry was able to make a crank without counterweights work

      It also helps in letting the clutch out without stalling the motor

    Every car company was still going thru a learning process at the time.

    It was all about momentum and stored energy, supposedly made driving easier. Just let the clutch out and go.

      Then it seems that flywheel weight was replaced with shear horsepower.

        Some flywheel weight is replaced with crankshaft counterweights. Clutch discs were also improved with damper springs. Recently I pulled mine out.. solid disc. I hope to see an improvement with a dampened disc and V8 pressure plate as I was told they have a smoother engagement.

          Make sure your V-8 pressure plates finger pins are not held in by E clips or you''l be down and out on the side of the road

        Model A lightened flywheel profile.
        by DaWizard
        Ok, after doing an extensive site search, I have come up blank, so asking here.

        I need some type of a drawing with dimensions to give to my machinist with the lightened flywheel profile. Everyone says "lighten the flywheel" but I can't find a drawing to dictate where and how much meat to remove.

        Thrill me and produce me a picture I can copy and print for the machinist.

        Multi Plate Clutch Info!
        by 2manycars
        The inside of the flywheel is the most critical part. If the internal splines are worn to where they have divots from the teeth on the clutch pack rattleing, the clutch will not release well. Also, that flywheel looks from the photo to be the early flywheel with out the releaf for the starter drive, so an early starter would be necessary. The transmission gears look good, so that is a plus, and the...

        Flywheel Surface Depth
        by OTTAWAED
        What is the correct factory distance between the flywheel face and the clutch cover plate mounting surface. Brattons states 1.123 in in their catalogue. I measured 1.179 on an old flywheel which, of course may have been altered. Ed

        Has anyone ever converted a Multi-Disc Clutch system to a Single Disc Clutch system on a 1928 Model A/AA Ford YET maintain that 1928 look on the outside of the chassis???

        If so, just what is the procedure to do so?

        Could it be wrote up to include in this fourm???

        Clutch, ... only for a little bit, then nothing
        by Bill CNC
        Hello All,

        I have a new pressure plate and clutch with about 200 miles on it. I noticed it was acting funny and started chattering so I pulled it out and saw a hot spot on the freshly resurfaced flywheel and one matching opposing spot on the pressure plate. I sanded both sides of the disc, and both the pressure plate and flywheel and put her all back together.

        Now, I have...

        Stuck Clutch
        by Roadster Rich
        My car is now in Venice Florida since last summer. I last drove it in September and had a pretty bad leaking water pump. So I repaired that and just went to go for a ride. Started up like a champ, but the clutch is stuck and pushing in the pedal does nothing. I am right on the gulf and in a garage that is not dehumidified so I suspect it is corrosion causing this.

        I seem to have heard...

        1933 ford model B 4 cylinder needs clutch adjustment?
        by ClaudeC
        Broke down yesterday.
        In heavy stop and go traffic for 1/2 hour...
        engine stalled.
        Could restart easily but could not get the car in gear...very heavy grinding.
        Had car towed home.
        Was able to restart and shift gears and drive into my garage.
        I suspect clutch could not depress enough?
        any suggestion about adjusting the clutch?

        by BillLee/Chandler, TX
        My car has a lightened flywheel and a V8 clutch. It came that way from an engine build from the mid-80's. The pressure plate has some chunks of steel welded on it, apparently for balancing. Note in the picture the slug of steel welded in at about the 9 o'clock position, and another welded into the hole over the spring at about the 3:30 position. I haven't looked closely (yet) to see if there is any...

        Bad clutch??
        by Tgenardi
        Just purchased a 1930 Model A with a 1980 Jeep engine and 1939 transmission from what I was told. It may have an adapter between bell housing and transmission. When you put the clutch in, you can change gears, but the vehicle doesn't move. The previous owner said it just went out as she had other potential buyers test driving the vehicle. The clutch pedal is kind of soft.
        I'm looking for some...

        Clutch Chatter Diagnosis
        by 40B1930
        After 60 miles of shake-down drives, I am hearing clutch disc chatter with the trans. in nuetral. When I press the clutch pedal in to the point where the slack is taken up the chatter stops. After driving the car for a few miles the chatter is gone (maybe the grease on the new throw-our bearing thins after warming)?
        1. All parts are new
        2. Clutch disc was centered
        3. Pressure plate...
